T FWF E/M JJJJJLJJ" MACHINE FOR WAX-TREATING THE EDGES OF HEELS.

To all whom it may concern Be it known that I, CARL A. MATSON, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented new and'useful Improvements in Machines for Wax- Treating the Edges of heels, of which the following is a specification.

This invention relates to a machine for wax treating and finishing the edges of the heels of boots and shoes.

The object of the invention is to provide a machine in which is embodied a work-rubbing member which will apply wax evenly to the edges of the heels of boots and shoes and which will also impart a rubbing, polishing and burnishing action to said edges when they are held against it.

The invention contemplates using a rotary work-rubbing member having a continuous, yielding, metallic periphery which will accommodate itself to the different curves of the edges of boot and shoe heels which may be held against it, and in combination with this work-rubbing member a yielding scraper is used which is so constructed and held as to conform to different shaped rims of rotary work-rubbing members or to the diiferentshapes assumed by the rim of the particular w0rk-rubbing member hereinafter described and having a yielding, resilient, metallic'rim.

In the embodiment of my invention hereinafter set forth in the specification and illustrated in the drawing, means are shown for applying melted wax to the periphery of the work-rubbing member, said means being substantially the same as described and shown in my co-pending application Serial No. 734,507, filed December 2, 1912, and in the machine of this invention the edges of the heels of boots and shoes are wax treated by means of the work-rubbing member coacting with a flexible scraper for removing the superfluous wax from the periphery of the rim of said rotary workru-bbing member, whatever the shape of said rim may be, the wax being applied in a melted condition and the superfluous wax being removed therefrom by means of said flexible scraper.

In addition to the function performed by the scraper of removing superfluous wax from theperiphery of the rim of said workrubbing member, said scraper is also mounted in such a manner as to constitute a means whereby the yielding resilient periphery of Specification of Letters Patent.

AppIication filed March 17, 1913.

the work-rubbing member is prevented from being pressed beyond a certain extent out of its normal shape by the heel of the shoe which is being finished upon said work-rubbing member.

It is desirable, in addition to rubbing the heel circumferentially thereof in the wax treating operation, to also simultaneously rub the heel transversely thereof, and it is the object of this invention to provide a work-rubbing member combined with a scraper which shall perform such an operation upon the edges of boot and shoe heels which are applied to its periphery.

The invention, therefore, consists in a machine for burnishing and wax treating the edges of the heels of boots and shoes such as described in the following specification and particularly set forth in the claims.

Referring to the drawings: Figure 1 is a side elevation of my improved machine for burnishing and finishing the heels of boots and shoes. Fig. 2 is a sectional elevation taken on line 22 of Fig. 1, both Figs. 1 and 2 being broken away to save space in the drawings. Fig. 3 is a plan View of the V work-rubbing member. Fig. 4 is a detail plan view of the scraper and its holder. Fig. 5 is a detail sectional elevation taken on line 55 of Fig. 4. Fig. 6 is a detail plan view of a modified form of work-rubbing member.

Like numerals refer to like parts through out the several views of the drawings.

In the drawings, 5 is the frame of the machine; 6 is the main driving shaft to which is fastened the work-rubbing member 7. The wax is contained in a wax pot 8 and is fed from a supply chamber 9 to an intermediate chamber 10 in which it is kept at a predetermined height by a float valve 11, the wax passing from the chamber 9 into the chamber 10 through a port 12 which is opened and closed by the float valve 11. From the chamber 10 said melted wax passes into the feed chamber 18 through a port 14. The wax is kept in a melted condition by means of a gas jet, gas being supplied by means of a pipe 15.

The shaft 6 is rotated by any suitable means, such as a pulley, and the work-rub bing member 7 which is attached to the front end of the shaft embodies a hub 16 which is fastened by a set-screw 17 to said shaft 6.

The rim of the worlcrubbing member 7 is formed by a flexible member, preferably consisting of a metallic strip 18 forming a helix one end of said metallic member being fastened, preferably by welding, to a ring 19, the other end of said metallic member being fastened to an annular flange 20 which flange is fastened by means of screws 21 to a cylindrical flange 22 forming part of the hub 16. The ring 19 fits in an annular recess 23 provided in a flange 24 and is fastened thereto by means of screws 25. The cylindrical flange 22 is provided with an annular recess 26 to receive and center the flange 20. The flange 24 is provided with a hub 27 which is adjustably fastened to the hub 16 by means of a set-screw 28. The helical member 18 is thus fastened to a holder, said holder consisting of the hub 16, the flanges 24, 22 and 20 and the ring 19. It will thus be seen that the helical member constitutes the periphery of the work-rubbing member 7 and is supported upon the holder hereinbefore described, which holder is fastened to the shaft 6 by the set-screw 17 and is rotated therewith. The adjacent convolutions of the helical member 18 contact with each other, so that the wax does not penetrate to the interior of the work-rubbing member when said work-rubbing member is used as a finishing tool, and the flanges 24 and 20, together with the ring 19, act to hold the convolutions of the helical member against lateral movementrelatively to each other. By adjusting the flange 24 toward the-flange 20 it will be seen that the different convolutions of the helical member 18 may be clamped against each other.

' The helical member 18 is preferably formed from a tube of the proper size which is placed upon a lathe and cut so as to form the different convolutions of said helical member. It is then placed in a lathe and its convolutions clamped against each other by any suitable means and the convex outer surfaceof the same is then turned thereon in said lathe. The inner diameter of thehelical member is made greater than the outer diameter of the flange 22. so that aspace 29 is provided in the finished work-rubbing memher which allows the different convolutions of thehelix to yield or move inwardly toward the median axial line of the workrubbing member without abutting against said cylindrical flange, 22.

Suitable means for heating the work-rubbing member 7 is provided, such as the gas pipe 30. It will be seen that the periphery of the work-rubbing member 7 is a continuous, yielding, metallic periphery and also that the periphery is resilient.

While I have described the work-rubbing member 7 as formed of metal, it will however, be evidentthat any material which is l hard as compared with leather and is there 1 fore capable of polishing or burnishing leather when rubbed thereagainst would be an equivalent of metal and may be used without departing from the spirit of this invention. Such a material may be found in fiber and may be used with very good results, although not so durable and satisfac' tory as metal.

The wax pot 8 is provided with a cover 31 which extends partly around the work-rubbing member 7. Said cover is locked in position by means of an arm 32 which is provided with a screw 33 adapted to bear against a boss 34 on the wax pot 8. When the screw 33 is in contact with the boss 34, then the cover is locked downwardly in position over the work-rubbing member 7 When it is desired to unlock the same and throw the cover 31 backwardly upon its pivot 35, it may be done by swinging the arm 32 to one side so that the screw will be disengaged from the boss 34. The cover 31 is provided with a slot 36 in which is slid ably mounted a holder 37 for a scraper 38. The scraper 38 consists of a strip of flexible material, preferably felt, and the opposite ends of said scraper extend into recesses 39 formed in the ears 40 of the holder 37. A flat strip of spring metal 41 extends along the outer edge of the felt strip 38 and projects at its opposite ends into the recesses 39.

Intermediate the ends of the holder 37 and of the scraper 38 is located a presser 42 which is provided with a slot 43 to receive the scraper 38 and also to receive the spring-backer 41. The presser 42 has a cylindrical shank 44. which extends through and slides within a hollow stud 45, said stud having screw-threaded engagement with the holder 37. A spring 46 encircles the shank 44 and extends into the chamber 47 provided in said stud 45. One end of said spring bears against the stud 45 the other against the enlarged inner end 48 of the presser 42. It will be seen that by turning the stud 45 in the proper direction the tension on the spring 46 may be increased or diminished as desired and also that the inner end of said stud will form a stop against which the en larged inner end of the presser 42 will abut when the spring 46 has been compressed to a certain extent. The stud 45, therefore, forms a stop to prevent the scraper 38 from being bent beyond a certain extent or to prevent the central portion thereof from being moved away from the median axial line of the work-rubbing member beyond a certain extent.

The holder 37 may be moved, together with the scraper 38, toward or away from the work-rubbing member by means of the adjusting screws 49, said screws having 1 screw-threaded engagement with the cover 31 and extending through slots 50 provided in the opposite ends of the holder 37.

- and are movable therein, see Fig. 2, although arrow at (Fig. 1).

said holder can be adjusted toward and away from the work-rubbing member, but

in the operation of the machine said holder is stationary, while the central portion of the scraper 38, or that part intermediate the ends, is movable transversely of said scraper, the scraper thus being able to assume different curves to fit varying forms of the periphery of the rim of the work-rubbing member.

It is evident that if sufficient pressure is brought to bear upon the periphery of the work rubbing member 7 by the heel of the shoe 52, said periphery will yield slightly, being allowed so to do by the spring 46, and the scraper 38 will bend between its ends to conform to the shape of the periphery of the rim of the work-rubbing member, so that the scraper 38 is held against the periphery of the work-rubbing member with a yielding pressure and also conforms to any shape which the rim of said work-rubbing member may assume, but said scraper can be positively moved away from said workrubbing member to assume different positions relatively to the periphery thereof by means of the screws 49.

While I prefer to use the form of workrubbing member with the strip forming the helical rim which has been hereinbefore described, it is evident that work-rubbing members having solid rims to fit different shaped heels may be utilized in combination with my improved scraper without departing from the spirit of my invention. A work-rubbing member such as referred to is illustrated in Fig. 6 in which 53 is the rim and 54 the hub.

The general operation of the mechanism is as follows: The heel of the shoe 52 is placed against the periphery of the workrubbing member and said work-rubbing member is rotated in the direction of the The wax is supplied to the chamber 10 in sufficient quantity so as to keep the level thereof in the feed chamber 13 always at the height of the line b (Fig. 2). The work-rubbing member 7 is kept heated by a gas jet from the pipe 30 and the wax is carried up on the periphery of said work-rubbing member until it encounters the scraper 38, when the superfluous wax is removed from the periphery of said workrubbing member and that portion of the work-rubbing member from which the superfluous wax has been removed then moves forward in the direction of the arrow 0; and

rubs the edge of the heel of the shoe 52 which is held against it, thereby placing upon the heel a thin and even film of wax and thoroughly rubbing it and burnishing it into the edge of the heel.

It will be understood that the periphery of the work-rubbing member 7, as a whole, will yield and conform to slightly varying shapes in cross sectional contour of the edges of different heels of boots and shoes which may be applied thereto in performing the burnishing and finishing operation. It will also be understood that as the member 18 is formed as a helix, when the work-rubbing member 7 is rotated there willbe a polishing action extending circumferentially of the edge of the heel and also a tendency to lay the fibers of the leather smoothly by reason of the action of the helically disposed convolutions of the member 18 which thus stand at an angle and tend to rub the edge of the heel transversely thereof.

After theheel has been wax treated by the work rubbing member 7 and an even coat of wax has been placed upon the edge of the heel and thoroughly burnished and polished thereon, said heel is afterward subjected to the action of a padding roll and brush to obtain a finer polish in a manner well known to those skilled in this art.
